Have a try and confirm the front and side of the glasses.
Confirmation data: pupil height, flat frame surface, size of frame surface, the harmony of nose arc, the contact area of nose support, size of temple bend. Finally, remember a big principle: You should have no sense of pressure, and in a small range of motion, the frame does not shift. Good glasses should be perfectly integrated with the face so that people can not feel the existence of glasses. Good design is invisible. The lens above 800 degrees will be slightly heavy, so it is not recommended to choose the elastic temple and smooth metal temple. The temple is too slender, and at the same time is all metal, easy to slide frequently.

After the examination, you will bring your optometry sheet and go to the optician to match your glasses. Note that the optical shop has professional qualifications. The refractive index of the resin lens, such as 1.49, 1.56, 1.61, 1.67, and so on, mainly depends on the degree. If the degree is not high, 1.56 will do. In addition, the sophisticated store will also measure the nose height, nose width, the distance between the eyes and ears, and the forward angle of the frame, which are also indicators of whether the glasses are comfortable to wear. It is recommended to try them on after they are fitted, and the time to try on them should be longer, so as to determine whether the glasses are suitable.

Fortunately, oversized glasses come in a variety of shapes. If you have a round face, choose a square frame or a passing frame.
